No, not that Granny. The other one

Truckers, the first of Terry Pratchett's novels to be adapted for TV brings to life the story of the Nomes. 15000 years ago the Nomes crashed to Earth in a scout ship from the starship Swan. Generations of them have come and gone with the passing years and the changing countryside. Suddenly faced with extinction, the ten surviving Nomes, guided by their reluctant leader Masklin, must face many exciting adventures during their search for a new home and hiding place in the big, bad world of the humans.
